QUALITY
CONTROL INSTRUMENTATION
Fast accurate measurement of the Worlds most
damaging contaminant  and its most beneficial!

Versaperm
Limited, a world leader in water vapour permeability is
launching an entirely new instrument for the fast and
accurate measurement of water vapour permeability 
which is both the worlds most damaging contaminant
and is often the crucial factor in QC
measurements. Additionally, It can measure
permeability for most gaseous elements.

Water vapour is omnipresent and highly invasive. Problems
in this area costs the UK alone considerably over £100M
every year.

The
Versaperm WVTR (Water Vapour Transmission) MK VI
meters highly automated computerised control can
cope with several samples at a time - and still give a
reading in as little as 30 minutes for some materials.
The conventionally gravimetric measurement technique
takes several days and gives significantly less accurate
/ reproducible results.

The MK VI needs very little re-calibration and requires,
at most, minimal training to give results that can be
accurate to better than one part per million (with some
samples a few parts per hundred million). Sensitivities
are typically in the range 0.05 - 3200g/m2/day.

A
wide variety of options is available, depending on the
specific applications, but both single and multi-sample
systems, plus a range of measurement chambers and sensors
can be supplied for testing samples from the size of a
thimble up to a pallet load and beyond.

As
well as vapour transmission, the equipment can be used to
measure the Equilibrium Relative Humidity (ERH) of
substances - that might otherwise be decomposed by normal
water content measuring techniques. Additionally the
instrument can be configured to measure the diffusion
rates of most gaseous elements (water, O2, CO2 etc).

The company also operates a laboratory service to measure
permeability for companies where the volume or logistics
of measurements does not demand a dedicated instrument.
